Was up and out for 7am this morning to give the F-Pace and Audi TT a wash. They look great in the sunshine. Spring has sprung!

However, how do you clean the brake calipers? I have the double helix wheels so I can get my mitt into the rear of the alloys but can't get the whole caliper. Obviously, I could jump in the car and roll it forward a few centimetres or take the wheels off (really?). Does anyone have any suggestions other than powerwash (which isn't really sufficient to restore them to their shiny red glory).

I use a non acid wheel cleaner and spray this on and ordinary hose pipe pressure is enough to restore the shine.
Better still if you have the pressure washer out but my at least weekly clean restores the red calipers.

Same here - I use a non acid wheel cleaner - Bilt hamber auto wheel- spray it on the wheel including the calliper - wait five minutes- and wash off with a hose pipe. Works great.

Agreed here - something like Gtechnic W6 Iron and Fallout remover works very well also. And if your are feeling extravagant search online for wheel woolies - makes cleaning alloys so much easier and safer!!

If they are bad try Valet Pro Dragon's Breath, and leave for 5 mins, agitate and then wash off.
Valet Pro's Bilberry is good for regular cleans.

The best way to keep alloys (and even brake calipers) clean in the long term is Gtechniq C5 Wheel Armour.

As a sidenote and testimony to this product, I had to have an alloy on my previous car refurbed and even after 4 years they rung to ask what I had treated them with as they were having issues getting paint to bond
